Polarized Light Microscopy (PLM) for asbestos in bulk samples:
EPA/600/R-93/116 Method.
Polarized Light Microscopy (PLM ) analysis is performed to identify, classify and quantify Asbestos fiber concentration in bulk building materials, domestic & Industrial insulations, sprayed & non-sprayed plasters, coatings, ceiling & flooring materials, Floor tiles, caulks and adhesives.
This method is used to quantify Asbestos fibers in bulk materials at a lower detection limit using PLM microscope. Point Count provides detection limit of 0.25%. Phase Contrast Microscopy (PCM):
NIOSH 7400 Method.
PCM analysis is performed to measure fiber concentrations in Clearance, Personal and Ambient air samples during and after abatement.
Utilizing EPA methods, we offer the capability to analyze Asbestos Bulk (PLM) samples, Fiber Count (PCM), Bulk Point Count, and Wipe Samples by PLM.
